Energy Measurement (5)
Biochemical (Biological) Oxygen Demand (BOD)
Carbonaceous BOD: aerobic heterotrophs
Decompose organic molecules to minerals (CO2) and residues
Obtain their cell carbon from the organic material
Nitrogenous BOD: obligate aerobic chemoautotrophs
Characteristics of nitrifiers (chemoautotrophs)
DO < 2 mg/L action slow
DO < 0.5 mg/L action ceases
Optimum pH: 8.0; pH < 7.2: slows down
More sensitive than heterotrophs to toxins
Slow growers (longer sludge age required)
